	Make a new generator.
Public Member Functions inherited from ph::SampleGenerator
	SampleGenerator (std::size_t numSampleBatches, std::size_t maxCachedBatches)
	SampleGenerator (std::size_t numSampleBatches)
virtual	~SampleGenerator ()=default
virtual void	rebirth ()
	Reset this generator to its initial state, reviving it from dead state. Calling this method starts a new life cycle–all existing sample stages and values are lost, and references to them are invalidated. New declarations can be made after, and new sample values can be generated.
void	genSplitted (std::size_t numSplits, std::vector< std::unique_ptr< SampleGenerator > > &out_sgs) const
bool	prepareSampleBatch ()
	Generates sample values for current sample batch. Advances all sample values in all stages to the next batch. Will potentially generate sample values for more than one batch at once (cached).
SamplesNDHandle	declareStageND (std::size_t numDims, std::size_t numSamples)
	Similar to declareStageND(), with default size hints.
SamplesNDHandle	declareStageND (std::size_t numDims, std::size_t numSamples, std::vector< std::size_t > dimSizeHints)
	Declares a N-dimensional sample stage. A sample stage contains information for how the samples will be used, number of samples, etc. These information can help the sample generator to produce sample values of better quality. This method can only be called before sample batches are generated (before any call to prepareSampleBatch()).
SamplesNDStream	getSamplesND (const SamplesNDHandle &handle) const
	Gets generated N-dimensional sample values in a stage. This method can only be called after sample batches are generated (after any call to prepareSampleBatch()).
std::size_t	numSampleBatches () const
std::size_t	maxCachedBatches () const
std::size_t	numRemainingBatches () const
bool	hasMoreBatches () const
